No. 397,588 11 Claims. (Cl. 3385) The present invention relates to an improved device for installing corner beads or the like.

It is an object of the present invention to provide a generally improved and efficient device to facilitate the installation of a corner bead or the like.

It is another object of the present invention to provide a highly novel and eflicient clamp r holder which may be readily attached to a corner bead or the like for the mounting of a plumb line which is attached to a plumb bob so as to assure a corner bead installation which is vertically true or correct.

It is another object of the present invention to pro vide means for mounting a line along a length of corner bead or the like so as to align the corner bead along the entire vertical extent thereof.

Other and further objects and advantages of the present invention will become readily apparent to one skilled in the art from a consideration of the following specification taken in connection with the appended drawings.

In the drawings, which illustrate the best mode presently contemplated for carrying out the invention:

FIGURE 1 is a side elevation view of a corner bead provided with a device or attachment pursuant to the present invention for mounting a plumb line and plumb bob on the corner bead;

FIGURE 2 is a view similar to FIG. 1 and illusstrates a pair of clamps or mounting devices pursuant to the present invention between which there extends a line to assure true linearity of the corner bead along the vertical extent thereof;

FIGURE 5 is a perspective view of a holder or clamp for mounting a plumb line on the corner bead; and

FIGURE 6 is a perspective view of a holder or a clamp which cooperates with the holder or clamp illustrated in FIG. 5 for extending a trueing line therebetween so as to assure correct linearity along the extent of the corner bead.

Referring now to the drawings in detail, the reference numeral 10 indicates a conventional section of wire lath which is provided with a conventional corner head 12. The wire lath is provided with conventional openings or apertures 14.

Pursuant to one highly novel aspect of the present invention there is provided a preferably metallic plumb line holder or bracket 16. As best shown in FIG. 5, the bracket 16 comprises an elongated body portion 18 which is provided with a laterally extending flange or arm 20. At the upper end thereof the body portion 18 is provided with an elongated arm 22 which is pivotally secured thereto as by a pivot pin 24, the arm 22 being freely movable on the body portion 18 as indicated by the full and broken line positions thereof in FIG. 5. At the free end thereof the arm 22 is provided with a hook 26. Between the flange and the arm 22, the body portion 18 is provided with a curved guide nose for locating portion 28 which is bent inwardly to overlie the body portion 18. Below the flange 20, viewing FIG. 5, the body portion is provided with a second guide nose or locating portion 30 which is also bent inwardly so as to overlie the body portion 18. The guide nose 30 is provided with an outwardly deflected tail 32 in which there is defined an aperture 34. A second aperture 36 is defined in the flange 20 and it is disposed closer to the guide nose 28 than to the guide nose 30. In addition, there is defined a V-shaped notch 38 in the upper marginal edge 40 of the flange 20. As best shown in FIG. 1, the distance between the notch 38 and the upper guide nose 28 is equal to the radius of the plumb bob 42.

A line or cord 44 is utilized to mount the plumb bob 42 on the bracket or holder 16. More specifically, one end of the line 44 is threaded through the aperture 36 and is knotted as at 46. The other end of the line 44 is tied to the plumb bob 42 as at 48. It will be noted that the line 44 also is threaded through the aperture 34 in the tail 32 of the lower guide nose 30, as best illustrated in FIG. 1.

Referring now to FIG. 3, there is shown a corner 51 of a wall or the like to which there is secured in conventional manner a corner wire lath section 10 which is provided with corner bead 12. In order to mount the bracket or holder 16 on the wire lath 10, the upper and lower nose guides 28 and 30 are engaged on the corner bead 12 so as to encompass the latter as shown in FIGS. 1 and 3. Consequently it will be apparent that the guide noses 28 and 30 serve to properly guide and position the bracket on the corner bead.

With a bracket 16 properly mounted in position on the corner bead wire lat-h 10, the plumb bob is now suspended therefrom. More specifically, the cord or line 4 4 as it extends from the tail 32 of the lower guide nose 30 is looped over the upper marginal edge 40' of the flange 20 and it is disposed within the V-shaped locating notch 38 so that the plumb bob 42 is freely suspended from the upper marginal edge 40 of the flange 20. As previously indicated, the distance along the upper marginal edge of 40 between the upper guide nose 2 8 and the notch 38 is equal to the radius of the plumb bob 42. Consequently the corner bead 12 is in true vertical disposition when the plumb bob 42 engages the corner bead 12 below the bracket or holder 16 as illustrated in FIG. 1. It will be apparent that if the plumb bob 42 is disposed either to the left or to the right of the position thereof illustrated in FIG. 1 the corner bead 12 is not in true vertical alignment and therefore must be adjusted until the plumb bob 42 is in the condition thereof illustrated in FIG. 1.

It may occur that in relatively long sections of wire lath 10 provided with a corner head 12 that the corner bead may be truly vertically aligned at the upper and lower ends but that intermediate portions thereof between the opposite ends of the corner bead may be out of alignment. For this purpose provision is made for the aligning device generally indicated by the reference numeral 52 in FIG. 2. The aligning device 52 comprises a bracket or holder 16 as previously described and a cord 44 which is secured thereto as previously described and a second bracket or holder 54. The second bracket or holder 54, as best shown in FIG. 6, comprises an elongated body portion 56 which is provided with an integral fixed arm 58 which extends at an obtuse angle therefrom. At the free end thereof the arm 58 is provided with a hook 60. At the upper or free end thereof the body portion 56 is provided with a curved guide nose or locating portion 62 which overlies the latter, as best shown in FIG. 6. Below the guide nose 62 the body portion 5-6 is provided with a lateral flange 64. An elongated recess 66 which extends upwardly from the lower marginal edge 68 of the flange 64 partially separates the body portion 56 from the flange 64.

Assuming now that the corner bead 12 is in true align- I lath 10.

ment since the plumbbob 42 engages the corner bead .as shown in FIG. 1, a determination can now be made.

as to whether the corner head is in true vertical disposition or alignment between the opposite end portion thereof. For this purpose the second bracket or holder 54 is mounted adjacent to the lower end 70 of the metal It will be noted and understood that the holder or bracket 16 was originally mounted adjacent to the upper end 72 in order to check the true vertical alignment of the corner bead 12, the plumb bob 42 extending to a position adjacent to the lower end of the wire lath as shown in FIG. 1 for the purpose of assuring true vertical linearity. Consequently, in order to now determine true vertical linearity between the upper end 72 ,of the wire lath and the lower end 70 thereof, an

the free end of the fixed arm 58 is inserted into one of the apertures .14 so as to engage the wire lath mesh 50 and the bracket 54 is pivoted into the position thereof shown in FIG. 2 in which the guide nose 62 is engaged on and encompasses the head 12 as shown in FIG. 4.

' The cord 44 is then removed from the notch 38 in the upper bracket 16 and is then engaged in the elongated recess 66 and looped over the upper marginal edge 74 of the flange 64 as best shown in FIG. 2. More specifically, it will be understood that the distance between the aperture 34 and the head 12 is equal to the distance between the elongated recess 66 and the head 12. Consequently the cord 44 extends in a straight line from the aperture 32 to the recess 66 into which the cord is looped after it is threaded through the recess 34 as shown in FIG. 2. Consequently if the head 12 is parallel to the cord 44, between the tail 32 and the recess portion 66 of the flange 64, the bead will extend vertically aligned along its entire vertical extent.

In view of the foregoing it will be readily apparent that there has been illustrated and described a bracket 16, a plumb line 44 and a plumb bob 42 cooperating with said bracket 16 in order to assure that a wire lath section 10 provided with a corner head 12 has the corner head 12 thereof in true vertical alignment or disposition. In addition, there has been illustrated and described a second bracket 54 which can be utilized in combination 'with the first bracket 16 and the line 44 extending therebetween so as to assure that the intermediate portions of the corner head 12 between the upper and lower ends thereof are also in true vertical alignment. It will be understood that various changes and modifications may "be made in the present invention without however departing from the basic inventive concept thereof as set forth in the appended claims.
